Previously, the home screen would show all the recently updated puzzles with those with offers being displayed first. This list didn't filter out any puzzles based on size, availablity, distance or anything else.
Now, you can switch on a filtered view which will show the same information as what you would see when you are on the search page looking at the offers list. You use the filter settings at the top of the search screen to reduce what shows up in the puzzle list. These same filters will be used on the home screen when you have filtered view turned on.
